Orbitals, the Basics: Atomic Orbital Tutorial â probability, shapes, energy; Crash Chemistry Academy In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.

Atomic clock Atomic clock. An atomic clock is a clock device that uses an electron transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS. The principle of

Molecular orbital theory In chemistry: Ionic and covalent bonding …properties of electrons is the molecular-orbital theory. According to this theory, electrons in a molecule, rather than being localized between atoms, are distributed over all the atoms in the molecule in a spatial distribution described by a molecular orbital.

Molecular Orbitals The electrons occupying the s H-H orbital represent the bonding pair of electrons from the Lewis structure of H 2 and is aptly named a bonding molecular orbital. The other molecular orbital produced, s * H-H shows a decrease in electron density between the nuclei reaching a value of zero at the midpoint between the nuclei where there is a nodal plane. Since the s * H-H orbital shows a decrease in bonding between the two nuclei, it is called an antibonding molecular orbital. Due to the decrease in electron density between the nuclei, the antibonding orbital is higher in energy than both the bonding orbital and the hydrogen 1s orbitals.

orbit orbit definition. In astronomy, the path followed by an object revolving around another object, under the influence of gravitation (see satellite). In physics, the path followed by an electron within an atom. The planets follow elliptical orbits around the sun (see ellipse).

Atomic Orbitals There are similar orbitals at subsequent levels - 3p x, 3p y, 3p z, 4p x, 4p y, 4p z and so on. All levels except for the first level have p orbitals. At the higher levels the lobes get more elongated, with the most likely place to find the electron more distant from the nucleus. d and f orbitals

Electron shell Example of a sodium electron shell model An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n. Electron shells have one or more electron subshells, or sublevels. These sublevels have two or more orbitals with the same angular momentum quantum number l. Electron shells make up the electron configuration of an atom. The number of electrons that can be in a shell is equal to .

Why are antibonding orbitals more destabilized, or higher energy, when they're between two atoms of very different electronegativities? A molecular orbital can be represented as a linear combination of atomic orbitals. Therefore, when assessing the interaction between a pair of atomic orbitals, we assign a coefficient to each of them. [math] \Psi = c_1\psi_1 + c_2\psi_2 [/math]

Atomic orbital An atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.rbitals are given names in the form: where X is the energy level corresponding to the principal quantum number n, type is a lower-case letter denoting the shape or subshell of the orbital and it corresponds to the angular quantum number ℓ, and y is the number of electrons in that orbital.

Molecular Orbitals Molecular orbital theory posits the notion that electrons in molecules likewise exist in different orbitals that give the probability of finding the electron at particular points around the molecule. To produce the set of orbitals for a molecule, we add together the valence atomic wavefunctions for the bonded atoms in the molecule.

Electron shells Electron shell is a group of atomic orbital, so that their orbits formed electron shell with the same value of the principal quantum number. The 1, 2, 3, 4 electron shell can hold 2, 8, 18, 32 electrons respectively, since the electrons are electrically attracted to the nucleus.

Introduction to Molecular Orbital Theory There are two molecular orbitals for hydrogen, the lower energy orbital has its greater electron density between the two nuclei. This is the bonding molecular orbital - and is of lower energy than the two 1s atomic orbitals of hydrogen atoms making this orbital more stable than two seperated atomic hydrogen orbitals.

Electronic Orbitals Orbitals that have the same or identical energy levels are referred to as degenerate. An example is the 2p orbital: 2p x has the same energy level as 2p y. This concept becomes more important when dealing with molecular orbitals.

How are antibonding orbitals formed? Chuck W. Share. Jun 29, 2014. An anti-bonding orbital is formed when two atoms approach each other and the overlap between atomic orbitals results in destructive interference. The destructive interference causes a node to form, which decreases the electron density between the two atoms.

Orbital The letters, s, p, d, and f designate the shape of the orbital. (The shape is a consequence of the magnitude of the electron’s angular momentum, resulting from its angular motion.) An s orbital is spherical with its centre at the nucleus.
